RUFUS G. MABCY, OF KANSAS CITY, MISSOURI.

PIPE-REAMER.

SPECIFICATION forming part of Letters Patent No. 325,948, dated September 8, 1885.

' Application inea July 23, isst. (No model.)

To all whom it may concern:

Beit known that I, RUEUs G. MARCY, a citizen of the United States, residingtat Kansas City, in the county of Jackson and State of Missouri, have invented certainnew and useful Improvements in Pipe-Beamers, of which the following is a specification, reference being had therein to the accompanying drawings. A

My invention relates to Teaming-tools, its object being to ream out the ends of pipes in such manner that when different sections of pipe are connected the passage of whatever may be inserted in the pipe will not be obstructed at the joints or points of connection.

In the accompanying drawings,making part of this specification, Figure l represents a side elevation, and Fig. 2 a longitudinal section of my invention.

In the figures, A represents a case or shell which has a shoulder, x a2, on its inside, said shell being larger from the shoulder down than at its mouth or upper end. Two female threads are cut in this shell, one in its mouth and the other in its lower end. The thread in the lower end is intended to engage a male thread upon the pipe E which is to be rea1ned.

B represents a shaft, which is formed with a head, C, upon its lower end. This head plays within the enlarged chamber of shell A. Its lower end is beveled and provided with a series of cutters, e.

a, represents a square shoulder upon the upper end of the head C.

D represents the feed sleeve which sur- 3 5 rounds the shaft B. This sleeve is provided with a male thread to correspond with the thread in the mouth of the shell C. The lower end of this sleeve rests upon the shoulder a of the shaft and acts as a feed for it.

The upper endY of shaft B is constructed in any suitable manner to receive a crank for turning same.

In using this device the shaft is iirst inserted in the case. Then the case is secured 45 to the pipe to be reamed. The sleeve D is then passed over the shaft and presses the' head with its cutters against the mouth of the pipe, Then by turning the shaft and gradually moving theA feed-sleeve the reaming is effected.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The shaft B, with its head and cutters, the shell A, with its enlargement and internal threads at each end, and the feed-sleeve D, the several parts being combined and adapted to operate substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

RUEUs e. MARGY.
